Your oldest and closest friends have really said they wouldn't take the brochure?
I remember that when I was a witness there was no arguing with me. I thought that I was right and that either the person was apostate or spiritually weak. You know, the standard replies of a witness.
The only way to get into their mind, i think, is to find where they have issues with the organization. ie, oral sex, birthdays, anniversary celebrations, lack of love in the congo, or doctinal things that they have decided were incorrect and their view is correct.
The biggest obstacle is to get over the "Wait on Jehovah". Even if they have questions they are continuelly told to do this. If something is not correct, then Jehovah will change it. You know the drill.
I think that was my biggest obstacle. I knew things were wrong but I was going to wait on Jehovah. Took 4 to 5 years to finally break away from that thinking.
Unfortunately, the only person you can change is yourself.
